--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Slightly adjusted testcase for the testsuite (gcc.c-torture/execute/ ?):

long long e, *d = &e;
int a, b, c;

int
main ()
{
  for (; c <= 5; c++)
    for (b = 0; b <= 5; b++)
      {
        for (a = 1; a <= 5; a++)
          ;
        *d = 0;
        if (c)
          break;
      }
  if (a != 6)
    __builtin_abort ();
  return 0;
}
